Best Fire-Rated Door Slabs for Interior Commercial Openings
The Calhome 30-by-80-inch fire-rated composite door slabs are the most directly relevant choices here: each lists a 20-minute fire rating, a solid wood stave core, and a finished surface. Choose among the left- and right-hand configurations and gray, olive green, white, or charcoal black finishes. The VIZ-PRO fire exit door is a different, frame-included option, but its supplied details do not confirm a fire rating, so verify its listing and local requirements before considering it for a rated opening.
| Product | Best suited for | Key distinction |
|---|---|---|
| Calhome Light Gray, Left-Hand | Left-hand inswing installations | 20-minute rating; finished slab |
| Calhome Olive Green, Right-Hand | Right-hand inswing installations | 20-minute rating; finished slab |
| Calhome White, Left-Hand | White finish and left-hand swing | 20-minute rating; finished slab |
| Calhome Charcoal Black, Right-Hand | Dark finish and right-hand swing | 20-minute rating; finished slab |
| VIZ-PRO Fire Exit Door | Buyers seeking a panic-bar door package | Fire rating not stated in supplied details |
Calhome Light Gray Left-Hand Slab
This 30-by-80-inch Calhome slab is best for an opening that calls for a left-hand, inswing door and a light gray flush-panel appearance. It has a 1-3/4-inch solid wood stave core and a stated 20-minute fire protection rating. The listed test standards are UL10C, NFPA-252, and ASTM-E-152.
The factory-applied, fade-resistant multi-step paint and seal finish is intended to avoid the need for additional painting. It was selected as a direct fit for shoppers seeking a fire-rated slab rather than a complete door-and-frame package. Limitation: the listing says the frame and hardware are sold separately.
Calhome Olive Green Right-Hand Slab
Choose this 30-by-80-inch slab for a right-hand, inswing configuration and an olive green finish. Like the other Calhome slabs listed here, it has a 1-3/4-inch solid wood stave core and a stated 20-minute fire protection rating. The product details identify UL10C, NFPA-252, and ASTM-E-152.
It is best for buyers who need the right-hand swing and want a factory-finished color rather than a plain surface to paint. The listing describes a fade-resistant, multi-step paint and seal process. Limitation: this is the slab only; confirm that the separate frame and hardware meet the requirements for the intended rated opening.
Calhome White Left-Hand Slab
This white Calhome slab is best for a 30-by-80-inch opening requiring a left-hand, inswing door. Its listed construction is a 1-3/4-inch solid wood stave core, with a stated 20-minute fire protection rating and named test standards of UL10C, NFPA-252, and ASTM-E-152.
The white factory finish is a practical choice when buyers want a finished surface without planning an extra painting step. It was selected as the light-finish alternative to the light gray left-hand model. Limitation: the product listing specifies that the frame and hardware are not included, so check the complete opening assembly before purchase.
Calhome Charcoal Black Right-Hand Slab
For a dark finish and right-hand inswing configuration, this 30-by-80-inch charcoal black slab is the most suitable option among the listed slabs. Its features include a 1-3/4-inch solid wood stave core and a stated 20-minute fire protection rating. The listed standards are UL10C, NFPA-252, and ASTM-E-152.
The factory finish is described as a fade-resistant, multi-step paint and seal process. This option was selected to give buyers the same stated core and fire-rating features in a darker color. Limitation: the slab does not include a frame or hardware, and the listed swing direction may not suit a left-hand opening.
VIZ-PRO Fire Exit Door With Panic Bar
This VIZ-PRO option is best for buyers looking for a door package with a frame and panic or crash bars, not a replacement fire-rated slab. Its listed wall-opening height is 81-11/16 inches and its adjustable width is 34-5/8 to 37 inches. The product details say it includes the frame, hinges, and panic bars, and describe a left-hinged, outward-opening configuration.
It was included as a related exit-door option because the listing identifies it as a fire exit door and supplies hardware and a frame. Important limitation: the provided features do not state a fire-resistance rating or certification. Do not treat it as an approved fire-rated door without verifying its documentation and suitability for the opening.
Buying Guide: How to Choose a Fire-Rated Door Slab
Does the slab fit the opening and swing?
Confirm the slab dimensions and handing before ordering. The four Calhome options listed here are 30 by 80 inches and inswing, but the left- and right-hand versions are not interchangeable without considering the opening and hinge orientation. Verify the required handing with the installer or project specifications.
What does “slab only” mean?
A slab is the door panel without a frame or hardware. The Calhome products explicitly exclude those components. For a fire-rated opening, check that the frame, hinges, latch, and other required parts are compatible with the door and approved for the intended assembly. A rated slab alone does not establish that the complete opening meets code.
Which finish should you choose?
Choose the finish that fits the space and project plan: light gray or white for a lighter appearance, olive green for a colored option, and charcoal black for a dark finish. All four listed Calhome slabs are described as factory finished, so additional painting is not presented as necessary.
What should you verify before installation?
Review the product documentation, fire-rating requirements, opening measurements, handing, and local building-code requirements. Confirm that the label and installation instructions match the project. Ask the local authority having jurisdiction or a qualified installer if the required rating or assembly details are unclear.

No. The product details state that the frame and hardware are sold separately.
Are these slabs all the same size?
The four Calhome products listed are each 30 inches wide by 80 inches high. Verify measurements against the existing opening and installation requirements.
Is the VIZ-PRO fire exit door confirmed as fire-rated?

How do I choose left-hand or right-hand?
Match the door’s handing and swing to the opening and project specifications. Confirm the orientation before ordering rather than relying on color or slab dimensions alone.
